[PATCH AUTOSEL 5.10 06/46] ARM: dts: Drop duplicate sha2md5_fck to fix clk_disable race

[Sasha Levin]

From: Tony Lindgren <tony@atomide.com>

[ Upstream commit 140a776833957539c84301dbdb4c3013876de118 ]

We have a duplicate legacy clock defined for sha2md5_fck that can
sometimes race with clk_disable() with the dts configured clock
for OMAP4_SHA2MD5_CLKCTRL when unused clocks are disabled during
boot causing an "Unhandled fault: imprecise external abort".

[PATCH AUTOSEL 5.10 07/46] ARM: dts: Fix moving mmc devices with aliases for omap4 & 5

[Sasha Levin]

From: Tony Lindgren <tony@atomide.com>

[ Upstream commit 77335a040178a0456d4eabc8bf17a7ca3ee4a327 ]

Fix moving mmc devices with dts aliases as discussed on the lists.
Without this we now have internal eMMC mmc1 show up as mmc2 compared
to the earlier order of devices.

[PATCH AUTOSEL 5.10 17/46] ARM: omap1: fix building with clang IAS

[Sasha Levin]

From: Arnd Bergmann <arnd@arndb.de>

[ Upstream commit 28399a5a6d569c9bdb612345e4933046ca37cde5 ]

The clang integrated assembler fails to build one file with
a complex asm instruction:

arch/arm/mach-omap1/ams-delta-fiq-handler.S:249:2: error: invalid instruction, any one of the following would fix this:
 mov r10, #(1 << (((NR_IRQS_LEGACY + 12) - NR_IRQS_LEGACY) % 32)) @ set deferred_fiq bit
 ^
arch/arm/mach-omap1/ams-delta-fiq-handler.S:249:2: note: instruction requires: armv6t2
 mov r10, #(1 << (((NR_IRQS_LEGACY + 12) - NR_IRQS_LEGACY) % 32)) @ set deferred_fiq bit
 ^
arch/arm/mach-omap1/ams-delta-fiq-handler.S:249:2: note: instruction requires: thumb2
 mov r10, #(1 << (((NR_IRQS_LEGACY + 12) - NR_IRQS_LEGACY) % 32)) @ set deferred_fiq bit
 ^

The problem is that 'NR_IRQS_LEGACY' is not defined here. Apparently
gas does not care because we first add and then subtract this number,
leading to the immediate value to be the same regardless of the
specific definition of NR_IRQS_LEGACY.

Neither the way that 'gas' just silently builds this file, nor the
way that clang IAS makes nonsensical suggestions for how to fix it
is great. Fortunately there is an easy fix, which is to #include
the header that contains the definition.
